A jointed connecting-rod 22, rid- Milwaukee, in the county. of Milwaukee and ing at one end on an eccentric on the driving 55 State of Visconsin, have invented a new and shaft 20, carries at the other end the cut-off useful Improvement in Street-Car Locomovalve in the steam-chest 14.

This mechanism consists of shield or roof 12, extending the entire length lever-arms 33 and 31, advisedly constructed of the car and open at both ends. A 'steamin the form of cases pivoted on an axleC and 5' eduction pipe 13 leads from the boiler to the connected, respectively, at their upper ends steam-chest 14,from which there are the usual by rods 35 and 36 to the cranks on the two passages into the steam-cylinder 15, having a ends of the shaft 26. These lever-arms or reciprocating piston provided with a pistoir cases are provided with mechanism for enrod 16, provided with a cross-head 17, travelgaging the axle in one direction, whereby 10o ing in suitable guides or slides 18 therefor. their oscillatory motion in one direction is A pitman 19 connects the cross-head 17 to a transmitted to the axle and it is caused to rocrank on the driving-shaft 20. The shaft 20 tate. v is journaled in suitable blocks therefor fixed For the purpose of obviating the discharge of steam from the cylinder directly into the air, which is objectionable on streets where persons and teams are necessarily in the immediate vicinity of street-cars, a system of tanks or condensers is provided adapted to receive the exhaust and dispose of it noiselessly and without forming a vapor or cloud in the surrounding air. For this purpose an exhaust-pipe 48 leads from the steam-cylinder to a shallow steam-tight condenser 01' tank 49, located just beneath the ceiling of the car and extending throughout its length and breadth, the bottom of which condenser 49 is inclined downwardly toward its central part at the sides, and pipes 50 50 lead therefrom downwardly into the condensers 51 51, located in or along the side walls of the car, and other pipes 52 lead from the lowest parts thereof to the drip-tank 53. It will be observed that this system of condensers is so arranged that the water formed therein will by gravity run into the drip-tank. From the drip-tank the water is raised through the pipe 5-1 and forced into the boiler by means of a pump, (not shown in the drawings, but of such form and arranged in such manner as is usually in locomotives,) the location of which pump is 'merelyindicat-edin the drawings at 55. Advisedly a steam-disseminatin g device, preferably a small paddle-wheel 56, is located in the condenser 49 at the mouth of the discharge-pipe 48, to receive and break up to a certain extent the current of discharging steam entering the condenser from the pipe 48. A vapor-exhaust pipe 57 leads from the drip-tank 53 into the case of the boiler discharginginto the smoke-passage, and is adapted for carry.- ing off vapor from the drip-tank into the smoke-flue of the boiler-furnace. Dampers or valves 58 and 59 are preferably located in the pipes 50 and 57, which are adapted for regulating the size of the aperture therein and of the passage of steam therethrough The stems 59- of the dampers turn by screwthread through the wall of the pipe, whereby the position of the dampers may be regulated and secured.

A steam-pipe 60 branches and leads from the exhaust-pipe 48, which is arranged to connect with corresponding steam-pipes passing through the several cars of the train and to conduct steam thereto for heating the cars, which steam is returned therefrom through the pipe 61 to the condenser 49. Steamcocks 62, 63, and 64. are inserted in the pipe 60, 4:8, and 13, respectively, for closing and opening the pipes for the passage of steam when desired.

. What I claim as new, and desire to secure by Letters Patent, is

1. In a steam-railway of steam-condensers consisting of a condenser located just beneath the ceiling of a car, comprising a single chamber extending substantially throughout the length and breadth of the car, other condensers located along the locomotive, a system sides of the car, comprising single chamhers extending substantially throughout the length of the car, a pipe connecting'the steamcylinder directly with the upper condenser, and a pipe or pipes running from the lowest parts of the upper condenser to the lower or side condensers, and suitable pipes. running from the lowest parts of the lower or side condensers to a lower steam-tight drip-tank, substantially as described.

2. In a steam-railway locomotive, a system of steam-condensers consisting of a condenser located just beneath the ceiling of a car, comprising a single chamber extending substantially throughout the length and breadth of the car. other condensers located along the sides of the car, comprising single chambers extending substantially throughout the length of the car, a pipe connecting the steam-cylinder directly with the upper condenser, and a pipe or pipes running from the lowest parts of the upper condenser to the lower or side condensers, suitable pipes leading from the lowest parts of the lower or side condensers to a lower steam-tight drip-tank, and a vapor-exhaust pipe leading from the drip-tank to the smoke-passage of. the boiler, substantially as described.

3. In a steam railway locomotive con- 'structed substantially in the form of a car having sides and an' elongated top, the combination of a condenser located just beneath the ceiling of the car, comprising a single chamber extending substantially throughout the length and breadth of the car, and a root raised centrally longitudinally above the ceiling of, the car and above the condenser, forming an-air-passage between the roof and ceiling or condenser of the car open at both ends, substantially as described.

4. The combination, with a locomotive, of an exhaust-pipe, as 60, leading from the steamcylinder to the train of cars drawn by the 10- comotive, which pipe continues in and becomes a return steam-pipe, as 61, a condenser in the top of the locomotive into which the return steam pipe discharges, other condensers located in the locomotive below the one at the top, and a drip-tank below all the condensers into which the water of condensation flows by gravity from the first or highest condenser through and from the other condensers, substantially as described.

5. In a steam street-car locomotive, an exhaust-pipe running from thesteam-cylinder to a condensing-tank, and a steam-disseminator consisting of a revolving paddle-wheel, as 56, arranged in the tank at the mouth of the steam-discharging pipe, substantially as described. g

In testimony whereof I affix my signature in presence of two witnesses.
